My first pedal, a "Whiteface" Rat by ProCo. It does everything from overdrive to distortion and even fuzz. Very good for bass too. I bought this as a kid at Sound Side (Stockholm). I'd tried every overdrive/distotion pedal that they had, and narroved it to two pedals: Ibanez Tubescreamer and the Rat. I went for the Rat! This one is still in my collection, and has become a real vintage treasure.
